<Conventional technology> For example, in a unit bath where a bathtub, washing area, bathroom wall, etc. are integrated, a unit bath equipped with a hand shower is inexpensive, but it does not give a sense of elegance when used as equipment in hotels etc. Focusing on this, the present applicant has proposed a good-looking shower unit as an optional part for a unit bath, and has already filed an application [Utility Application No. 1-86098 (see Japanese Utility Model Application No. 3-27684)].

This shower unit is shown in FIG. 4 and will be explained. As shown in the figure, the shower unit 10 includes:
A large number of shower nozzles 11 to 13 that realize various hot water release forms such as cascading hot water that releases hot water in a concentrated manner like a waterfall, squall shower that releases hot water as large particles, and mist shower that releases hot water as a mist. , an operating section 14 having a selection switch for selecting the mode of use, a setting switch for setting the temperature, etc., are mounted on a vertically elongated box with a high-class appearance.
As shown in FIG. 5, this shower unit 10 is attached to a bathroom wall 20 using bolts (not shown) or the like.

The internal hot water pipe A connected to the shower nozzles 11 to 13 of the shower unit 10 is connected to the external hot water pipe B provided on the back side of the bathroom wall 20 outside the bathroom via a bellows-shaped connecting pipe C. . Furthermore, the connecting portion between the connecting pipe C and the external hot water pipe B is located within the through hole 21 provided in the bathroom wall 20.

<Problem to be solved by the invention> By the way, in the above-mentioned conventional configuration, since the connection part between the connection pipe C and the external hot water pipe B is located in the through hole 21 of the bathroom wall 20, the connection If hot water leaks due to deterioration of the gasket (not shown) provided at the part, it may flow out of the bathroom through the through hole 21. Such water leakage may corrode the pillars and walls of the house if they exist outside the bathroom.

The present invention was devised in view of these circumstances, and the purpose of the present invention is to prevent water from leaking outside the bathroom by guiding it inside the bathroom even if water leaks.

<Means for Solving the Problems> In order to achieve the above object, the present invention provides a plurality of shower nozzles with different hot water discharge forms, and an operation for selecting one of the hot water discharge forms and setting the temperature. A shower unit in which a part and a part are provided in a vertically elongated box is attached to a bathroom wall, and has the following configuration.

The installation structure of the shower unit of the present invention is such that a bottomed cylindrical hot water receiving member is attached to a through hole for hot water pipe insertion provided in the bathroom wall where the shower unit is installed so that the opening faces into the bathroom. , an external hot water pipe passes through a rear wall surface along the vertical direction of the hot water receiving member, and connects the external hot water pipe and an internal hot water pipe connected to the shower nozzle inside the hot water receiving member; It is characterized in that a water leakage prevention treatment is applied to each of the penetration portion of the external hot water pipe and the attachment portion to the through hole of the bathroom wall.

<Function> In the above configuration, when hot water leaks from the connecting portion between the internal hot water pipe and the external hot water pipe of the shower unit, the leakage water is caught by the water leak receiving member because the connecting portion exists inside the water leak receiving member. The water will be discharged into the bathroom through this opening.

Even if some of the water leaking from the connection part tries to flow outside through the external hot water piping, the penetration area of the water leak receiving member through which the external hot water piping is penetrated is treated to prevent water leakage, so it will not leak from this route. It also prevents water leakage from flowing outside.

<Example> Hereinafter, an example of the present invention will be described in detail based on the drawings.

FIG. 1 shows an embodiment of the present invention. In this figure, the same reference numerals as those given in FIG. 5 of the conventional example refer to the same parts and portions, and detailed description thereof will be omitted here.

The structure of this embodiment, which is different from the conventional example, is mainly that the connection part between the connection pipe C located in the through hole 21 of the bathroom wall 20 and the external hot water pipe B is enclosed, and hot water leaking from the connection part is caught and the inside of the bathroom is A leak receiving member 30 that guides the water to the side is provided in the through hole 21.

Specifically, the through hole 21 in the bathroom wall 20 is made larger than the conventional example shown in FIG. Face the back wall 31 side to the bathroom wall 2
A flange 32 formed at the periphery of the opening of the water leak receiving member 30 is fixed to the bathroom wall 20 with bolts or the like.

An external hot water pipe B is passed through approximately the center of the back wall 31 of this water leakage receiving member 30, and a connection pipe C connected to the internal hot water pipe A and the external hot water pipe B is connected inside the water leakage receiving member 30. The parts are located. A rubber gasket 4 is provided at a portion of the water leak receiving member 30 through which the external hot water pipe B penetrates to seal a gap in this portion.
0 is attached, and a rubber gasket 41 is also interposed between the flange 32 and the bathroom wall 20 to prevent water leakage around the through hole 21 of the bathroom wall 20.

According to the above configuration, if hot water leaks from the gasket (not shown) disposed at the connecting portion due to deterioration or the like, the leakage water is caught by the water leak receiving member 30, and the water leak receiving member 30 opens as shown by the arrow. Lower cover 15 of shower unit 10
guided inward. Incidentally, a plurality of drain ports 16 such as holes and slits are provided at the bottom of the lower cover 15, and the leaked water is discharged into the bathroom through the drain ports 16. In this way, leakage of water to the outside is prevented.

By the way, in some unit baths, as shown in FIG. 2, a storage panel 50 having multiple upper and lower storage recesses 51 is attached to the bathroom wall 20. In some cases, the shower unit 10 is hooked onto a fall prevention bar 52 using a locking tool 17.

In this case, for example, the shower unit 10 will close three storage recesses 51, so the back wall of the third storage recess 51 from the top among the storage recesses 51 closed by the shower unit 10. 5
3 is provided with a hole 54 through which the external hot water pipe B is penetrated,
By locating the connecting portion between the external hot water pipe B and the connecting pipe C inside this storage recess 51, this storage recess 51 can be configured to function as the water leakage receiving member 30 described above. In this case as well, a rubber gasket 40 similar to the above is attached to the hole 54 where the external hot water pipe B penetrates, and a rubber gasket 41 is also interposed at the attachment site between the back plate 18 of the shower unit 10 and the storage panel 50. This is the same as in the above embodiment.

Then, a hole 19 (or slit) is formed in the back plate 18 of the shower unit 10 at a position corresponding to the third storage recess 51 from the top to allow the leaked water to flow into the lower cover 15 of the shower unit 10. The leaked water may be allowed to flow into the lower cover 15 side through the hole 19, and then drained from the lower cover 15 into the bathroom through a drain port 16 provided at the bottom thereof. In addition to this, it is also possible to form a drain groove on the opening side of the lower shelf of the third storage recess 51 from the top to drain leakage water that accumulates in the storage recess 51 into the bathroom. It is.

<Effects of the invention> As explained above, according to the invention, when hot water leaks from the joint between the internal hot water pipe and the external hot water pipe, this leakage water is prevented from flowing outside the bathroom. It can be discharged inside the bathroom. In this way, we take into consideration the possibility of water leakage,
Even if pillars and walls of a house exist outside the bathroom, it is possible to effectively prevent them from being corroded by water leakage.
